HAND-STAMP.

Specification of Letters Patent.

Patented Feb. 25, 1908.

Application filed June 4: 1907. Serial No. 377257.

To all whom it may concern:

Be it known that we, RICHARD L. LAMB and EUGENE M. TILDEN, citizens of the United States, residing at Washington, District of Columbia, have invented certain new and useful Improvements in Hand-Stamps, of which the following is a specification.

This invention contemplates certain new and useful improvements in hand stamps and relates more particularly to that class of such stamps in which a rubber printing surface is secured to a base or carrier.

The invention has for its object the production of a hand stamp of the character referred to in which the carrier is provided with a maximum bearing surface.

A further object is to provide simple and efficient means for attaching the printing surface to the base or carrier.

A further object is to provide the base or carrier with a removable handle.

A further object is to provide means to look the handle in position and at the same time serve as a supplemental securing means for the printing surface.

The invention will be hereinafter fully set forth and particularly pointed out in the appended claims.

In the accompanying drawings 2-Figure 1 is a perspective view of a hand stamp illustrating the particular type employed in our invention. Fig. 2 is a transverse sectional view. Figs. 3 and 4 are similar views of slight modifications.

Referring to the drawings, 10 designates a handle having a threaded shank 11, which engages a correspondingly threaded opening 12 in a base or carrier 13.

It will be noted that the threaded opening 12 extends entirely through the base or carrier 13, and that the threaded shank 11 is of a length corresponding to the depth of said opening 12, so that when in position in the opening, the lower end of the shank is flush with the bearing surface of the member 13, which forms a wide, continuous bearing surface for said member 13. The side edges of said base or carrier are cut away to form horizontal shoulders 14 and outwardly inclined sides 15 of a lower extension 16. In Fig. 1 is illustrated a stamp of the cushion type-a. 0., one in which a piece of sponge rubber 17 is interposed between the printing surface 18 and the base or carrier 13. In this form the cushion is provided with side flanges 19 which are under-cut, as indicated the flanges down out of engagement with the sides. If it is desired, however, to provide additional securing means, a staple 21 having a long arm 22 passed through an opening in the base or carrier 13, and into the shank portion of the handle, thereby looking it in place, and a short arm 23, the whole impinging against the flange 19, is employed. The body of the staple fits in a groove in the base or carrier, and can be covered by shellac or other suitable material to present a neat appearance. In this form, when it is desired to remove the printing surface it is first necessary to withdraw the staple sufiiciently to disengage the flange 19, and the printing surface may be removed in the manner heretofore described. If deemed expedient the short arm 23 may be extended to project all the Way through the-flange 19 and into the extension 16 of the base or carrier, and thus more firmly secure the printing surface to the base or carrier.

In Fig. 4 slight modification or reversal of the structures-illustrated in Figs. 1 and 2 is shown, the same consisting in providing the printing surface 18 with a hump or protu berance 24 which fits in a recess 25 having a restricted entrance. This recess on account of its tapering width corresponds to the undercut recess 20 illustrated in Fig. 2.

The advantages and operation of the herein improved hand stamp will be readily apparent to those skilled in the art to which it appertains. It will be particularly noted that simple and eflicient means have been produced for attaching the printing surface to the base or carrier without the use of solder and in such manner that they may be detached at will. It will also be observed that the inclined sides of the lower extension in addition to serving as a locking means pro vide a maximum bearing for the printing surface. It will be further noted that a removable handle is provided for the base or carrier, and efiicient means forsecuring the same against removal, said securingineans also aiding to prevent removal of the printing surface. It will also be observed that by providing a threaded engagement between the handle and base or carrier, the use of glue or other cements, which dry out, crack and deteriorate, thereby becoming useless, is avoided.

Various other modifications may be resorted to in the carrying forward of the invention and it will be understood that any changes in the form, proportion and minor details of construction may be made without departing from the spirit of the invention or sacrificing any of the advantages thereof.

What is claimed as new and patentable, 1s:

' 1. A hand stamp comprising a base or carrier, a handle detachably connected with said base or carrier and a resilient member provided with a rinting surface and formed with offset portions releasably sprung into engagement with the lower portion of said carrier.

' 2. A hand stamp comprising a base or carrier rovided with a reduced portion, a hand e detachably connected with said base or carrier and a resilient member provided with a printing surface and formed with offset flanges releasably sprung over the edges of said reduced portion.

' 3. A hand stamp comprising a base or carrier, a handle detachably connected with said base or carrier and a resilient member provided with a printing surface and releasably secured to and held by frictional contact to said carrier.

4. A hand stamp com rising a base or carrier provided with a recliiced portion hav irig inc ined edges, and a resilient member rovided with a printing surface, said mem- -Ber being releasably sprung over said in clined edges.

5. A hand stamp comprising a base or carrier provided with a reduced ortion having outwardly flared edges, an a resilient member provided with a printing surface, said member being provided with offset flanges sprung over said flared edges.

6. A hand stamp comprising a base or carrier, a handle detachably connected with said base or carrier and a printing surface releasably sprung into frictional locking engagement with said base or carrier.

7. A hand stamp comprising a base or carrier provided with a reduced ortion having outwardly flared edges, an a re silient member carrying a printing surface, said'member being provided with undercut flanges normally and releasably engaging said flared edges.

8. A hand stamp comprising a base or carrier, a printing surface secured thereto, a handle removably secured to said base or carrier, and a staple having one arm engaging said'handle and the other arm engaging said printing surface.
